BATTERY CHANGE

The miniature battery which powers your watch should last approxi-
mately 3 years.  However, because the battery is inserted at the factory
to check the function and performance of the watch, its actual life once
in your possession may be less than the specified period.  When the
battery expires, be sure to replace it as soon as possible to prevent any
malfunction.  For battery replacement, we recommend that you con-
tact an AUTHORIZED SEIKO DEALER and request SEIKO SR927W
battery.

3

Years

*

If the stopwatch is used  for more than 2 hours a day, the battery life
may be less than the specified period.

*

After the battery is replaced with a new one, set the time/calendar
and adjust the stopwatch hand position.

Battery life indicator

When the battery nears its end, the small second hand moves at two-second
intervals instead of normal one-second intervals.  In that case, have the battery
replaced with a new one as soon as possible.

*

The watch remains accurate while the small second hand is moving at two-second
intervals.

HOW TO USE THE TELEMETER

Before beginning, check that the stopwatch has been reset.

START

(Flash of light)

STOP

(Crash of thunder)

Press button A to start the
stopwatch as soon as you see
the light.

When you hear the sound,
press button A to stop the stop-
watch.

Read the telemeter scale that
the stopwatch second hand
points to.

Approx. 3 km

Please note that the stopwatch second hand moves in 1-second increments and does
not always point exactly to the graduations of the telemeter scale. The telemeter scale
can be used only when the measured time is less than 60 seconds.
